The new patent pending Speedfil Z4 Cage is the first cage optimized for BTA (Between-The-Arms) aero hydration. The Z4 Cage works with standard water bottles, as well as the Speedfil A2.
The Speedfil Z4 integrates a detachable arm which can hold a Garmin® Quarter Turn Bike Mount* to the top of the cage when used in a BTA configuration. This not only saves precious space within the aerobars but also provides easy access.
Data is now where it should be – easily viewable and easily accessible.
